Abstract
A method for molding a resin composition comprising a polyolefin and an inorganic filler to form a thin molded article, which comprises shooting said resin composition into a mold at such a high speed that its flow rate at the gate portion of the mold is at least 100 meters per second, thereby reducing the occurrence of short shots and the occurrence of mold flashing and making possible molding within a shorter period of time.
